Agreed on this. What's surprising to meis their success despite the logged in experience not being better at all. We're getting married, so my fiancée is (obviously) using pinterest for everything - her dress, themes, you name it. And the wedding planner we work with uses Pinterest too, we (try) to share it with them so they get an idea. Even such a simple feature as sharing a board is a nightmare and wastes 5-10 min…
Happy to help you share a board or pin from outside Pinterest. I've absolutely never had a problem with any of the things you mention. My problem with Pinterest is that it is way too commercial now with lots of links to buy and spam contained within images. I used to enjoy it but not so much now.
What I witnessed is constant struggle between my 30yo fiancee and our 50yo wedding planner. It happened multiple time, so there is an obvious issue either on the sharer's side or on the receiver side.
